GOGGLES.

Application filed. September 5, 1924. Serial No. 736,031.

This invention relates to improvements in goggles and has particular reference to that type of goggle used for industrial eye protection purposes.

One object of the present invention is to provide an eye protection goggle which will be interiorly ventilated and so constructed as to prevent entranceof injurious light rays and foreign substances behind the lens.

Another object is to provide such a device with non-metallic eye cups which will be suitably reinforced in the lens receiving end.

Another object is to provide a non-metallic eye cup for a goggle having an improved lens holding means.

A further object is to provide a goggle which will be strong and durable in service, economical of manufacture and an improve ment in the art. I

Other objects and advantages will be apparent from the following description taken in connection with the accompanying drawings, wherein are shown several einbodiments of the device.

In the drawings, forming a part of this invention,

Figure 1 is a top plan view of a goggle made in accordance with my invention;

Figure 2 is a side elevation thereof;

Figure 3 is a sectional view on line of Figure 1;

Figure 1 is a sectional View on the line AA of Figure 1;

Figures 5 and 6 are views similar to Figure 3 and illustrating two possible modifications.

Similar reference characters designate corresponding parts throughout the several views.

In producing my improved goggle 1 provide a pair of eye cups 10, preferably made of tubular material, and having their rear edge suitably curved as at 11 to readily fit the contour of the face of the person wearing same, and this edge 11 may be bent back upon itself as at 12 (Figure 3), or it may be suitably padded and reinforced in any other desirable manner known to those skilled in the. art.

Referring especially to Figures 3 and 4-, I provide an annular member 13 arranged interiorly of the eye cup 10. said annular member being preferably but not necessarily formed of metal, such as aluminum. This annular member is grooved approximately midway of its length so as [0 form an air chamber 141, which is bounded. on three sides by the material of the annulus 13 and upon the fourth side by the inner periphery of the eye cup. By offsetting the material of the annulus 13 as I have to provide the air chamber 1 1 I also form a lens receiving seat 15, upon which is placed any type of eye protection lens 16. The forward extremity of the ring 13 is interiorly threaded as at 17 and engageable by a clamping annulus 18 which is adapted to hold the lens 16 firmly against its seat 1!" In this form of the invention the exterior of the clamping; member 18 comes flush with the exterior of the eye cup 10, as clearly shown at 19.

The member 13 is provided with openings; 20 whereby circulation of air is permitted between the air chamber 14 and the interior of the eye cup. Also the eye cup 10 is proway it will be obvious that a suitable amount of air will be allowed to circulate from the exterior to the interior of the goggle to allow for ventilation, but due to the fact that the openings 20 and 21 are out of alignment injurious light rays will not enter the goggle behind the lens, neither will foreign substances such as fine metallic chips, emery, dust, etc, be allowed to get in.

The ring 13 serves to suitably reinforce the forward end of the eye cup 10 and for that reason is made to be a fairly good mechanical fit, just slipped into place by hand and held by a staple or other suitable fastening means 22. I preferably pro vide the fastening means 22 on the inner side of the eye cup and form it into an eye so as to be able to" connect thereto the entremity of a flexible bridge member 23. Any suitable means may be used for holding the goggle in place, such as elastic bands 24- or temples, whichever may be preferable.

In the modification illustrated in Figure 5 I have formed the eye cup 10 with a groove 26 having inwardly extending openin 's 27 to allow for the passage of air to the interior of the goggle. Furthermore, I have formed a ring member 28 which is simply threaded at its forward end 29 for the engagement oi the lens clamping ring :30. In this case the air chamber is founed by the clamping member 30 instead of by an in ternal annulus as in the previous form, said clamping member being provided with the necessary openings 31 out oi alignment with the openings 2?, for the purpose previously set forth.

In Figure 6 I have illustrated still anot modification wherein the eye cup 10 in perfectly smooth PGllUllGlfJ, both int rior and exterior, and surrounded by a ring member 32 which is centrally arched as at 83 to form the v ntilation chamber In this case also the necessary apertures are formed in the arched member 83 and in the eye cup 10* to permit of ventilation, and the lens 16 is seated directly the "front e'clgz'e oi the eye cup l0 instead of on a recessed seat.

From the foregoing it will be obvious that l have produced an improved construction or eye protection goggle which will be well ventilated and,- therefore, extremely ci a for-table to workmen and especially adapted for use in hot work, such as welding and adjacent to various kinds of furnaces in industrial plants, but because of the staggered reationship of the openings injurious if rays will not be able to pass through the sides otthe eye cup and the construction such that it will be easy and economical of manu-- facture. Obviously changes may he made in the proportion, arrangement and combination of parts, and I herein reserve the right to make such changes falling witnin the scope of the appended claims without departing from the spirit of my invention.
